Rename nand.h as flash/nand/core.h, chase consumers. The public APIs
need to be sorted out with imp.h, but this allows other changes to
begin improving the separation between policy and mechanism.
Moves #include <target/target.h> and #include "driver.h" into the
internal headers or source files, removing it from <flash/nand/core.h>.
Modify the arm_nand_data struct to better support both read and
write operations while using the same struct. An additional
field was added, and initialized, to record the last operation
so that the correct code can be loaded to the working area.

Changes from the flat namespace to heirarchical one. Instead of writing:
#include "arm_nandio.h"
the following form should be used.
#include <flash/arm_nandio.h>
The exception is from .c files in the same directory.
